'FAT-SKINNING MACHINE.

SIEGIFIGATION forming part of Letters Peregr ne. 657,322, dated September 4, 1900.

Application filed April 2, 1900. Serial No. 11,173- \llo m T ctZZ whom, it may concern:

ful Improvements in Fat-Skinning Machines, of which the following is a specification.

My invention relates to certain new and useful improvements in machines intended for use in packing-houses for skinning back fat or other fats from which the skin is to be cut and for other kindred purposes; and my invention comprehends the employment of a' rotatable drum and a yielding pressure-roller between which and the periphery of the drum" the pieces of fat or carcass are fed and inthe employment of alternately appearing and disappearing pins or devices which automat ically engage the skin of themeat'from be-" low and carry the meat to a suitable knife,

fixed or adjustable, by means of which the skin is severed or separated from the fat.

The invention further includes a perforated pipe exterior and proximate to the knife and adapted to discharge jets of steam or water,

preferably hot, upon the knife for the pur-' pose of heating the same sufficiently to cause the fat to slightly melt as the knife separates the skin from the fat and moistening the knife to facilitate the operation and maintaining the knife in a clean condition.

The invention also includes a means for positively operating the pins or teeth which engage the skin from below, whereby the said" pins are projected or caused to appear'be yond the outer surface of the drum to en-- gage the skin during the period thepiece of: meat is being carried to and operated upon by the knife, and said pins'are subsequently operated and caused to be retracted or disappear below the outer surface of the drum ing my invention. Fig. 2 is a vertical sectional View of the same on the line y y of Fig. u 3. V Fig. 3 is a horizontal sectional view on the ;line 00 0c of Fig. 2. Fig. dis a sectional detail of a portion of the drum and the roller and .showing the pins engaging the piece of fat.

/ In carrying out my invention I constructa firm base or bed A, of any suitable or desired form material, or construction, which base and the vertical sidesB constitute the essentials of an exterior stationary frame or cas- .ing, within which is rotatably mounted a drum or cylinder 0, which I will presently describe. The vertical sides B are formed or provided with journal boxes or bearings D for the journal ends of a horizontal transverse shaft E, to which power is applied, as by means of a driving-pulley a. The shaft is also supplied with or has secured to it means for operatively supporting the drum or cylinder,

so that it will rotate between the innersides' of the main frame or casing.

As herein shown, these means consist of a spider F, the ihllb of which is fixed to the shaft, while the 'arms extend to and are fixed to the inner periphery of the drum, against the outer pefriphery of which latter the skin side of the meat is held during the operation of trimming the fat from the skin. In conjunction with this drum or cylinder I employ a pressure-roller G, lying between the inner surfaces of the sides B and having its shaft- I journals 1) extending through slots 0, formed jin said sides radial to the axis. of the drum. lThese journals are rotatively mounted in short sleeves d,Wl1i0l1 in turn are fixed in boxes or bearings H, having stems or shanks e. slidably mounted in guides f, secured to the outside of the sides B. Around the shanks or stems c are placed coiledsprings e, the :tension-ofwhich-is regulated to any desired extent by means of collars g and setscrews it. From this description it will be apparent that the pressure-roller Gis yieldingly mounted and normally presses. against the outer periphery of the revoluble drum or cylinder 0, and said roller is capable of accurate adjustment against the drum by reason of the (p g a .p jee ed 1hr0n-shthe flatte 91 when the said pins are,retnacted orgcavseg to disappearhy the eperat omof thecamslMthe a said outer ends ofthe lever-armscontaetmrth -ateeth. 4 1 v a a Secured 1,150 the sides Bminqeither a fixed or" adgj ustahle position iislajknifetor c n tterfi the the gpresslrrewroller.

This frameicorisistsof; a lever-arm I, disposed near the inner face of each of the sides B and connected together at one end by means'of a bar or red J, .having fixed toit or otherwise carrying a series of pins'orteeth K, which project substantially at right angles to thebar or rod and lie in' line with a corresponding series of holes-a made through the drum or cylinder. Till e outer surface of the drum in advance of these holes is shown aszdepressed at grand the holes are made in ashoulder at the base of this depression, and the outer ends of the pins or teeth are beveled er iother wise made with sharp points adapted to better-engage the back or skin side of the piece of meat, and carry it during the skinning eperation.-
